Well I seem to be much like you, except my main SG is a really good shooter but my power forwards, center(trainee), and sf are good all around. So really I but it as run & gun, base offense, and during some scrimmages other tactics. How old are your Center and Power Forward? If they are 18 or 19 you should train them for inside scoring and defense/rebounding. If they are around 30 you should get some good trainees that don't need like 5 different skills trained. When I bought my trainees I bought some good ones for 1000-15000$. But if you want some practice you can scrimmage against me during the season
